Oyez does this for all cases. They also publish the oral arguments (which the Supreme Court itself releases) as a podcast feed, which I highly recommend. It's great listening even if you're not legally trained.

scotusblog.com also blogs about every case.

Oyez also syncs the audio podcast feed with the transcript, which I found to be useful in keeping focus on the minutiae of a hearing.
